to the left in Fig. 1, the curved wall h bears upon the pins f, andthereby depresses the upper end of the'clamp-lever andraises the lowerend thereof from the work When the handle-bar e is thrown to the rightin Fig. l, the roller g rides up under the lower cam-surface of theupper end of the clamplever d, and thereby raises the said upper end andpresses the free end of the clamp-lever d xgainst the work, as shown inthe full lines in IVhat I claim is` To @ZZ whom t may concern,.-

Be it known that I, JOHAN HENRIKSEN PEIOK, a subject of the King ofDenmark, l and a resident of Binghamton, in the county of Broome andState of New York, have invented certain new and useful Improvements inBench-Clamps, of which the following is a specification, reference beinghad to the accompanying drawings.

y invention relates to improvements in clamps for holding wood or othermaterial upon a bench or like support during the'time that it is beingworked upon by the artisan; and the object of my invention is to producea clamp of this kind which shall be simple in construction, cheap inmanufacture, and efficient in operation.

In the drawings illustrating the principle, of my invention, and thebest mode now known to me' of applying that principle, Figure 1 is asideelevation of my new clamp, and Fig. 2 is a front elevation of thesame.

The bench a is formed with a hole through which passes the rod b, fromthe upper end of which extends a curved arm c, pivotally mounted inwhich is the clamp-lever d. Mounted free to swing upon the upper en i ofthe rod b is the handle-bar e, the lower part of which is slotted toreceive the pins f, which project from the upper end of the clampever d.The handle-bar e carries a roller g, (see Fig. 2,) which is adapted tobear against the under surface of the upperend of the clamp-lever d, andwhich, being given a cam action by said handle-bar, may be called afoam-roller.

The operation of the clamp will be readily understood from the foregoingdescription and an inspection of Figpl, in'which the reis shown in dot--bar e is thrown nation of a supporting-rod formed with an arm; ahandle-bar mounted free to swing upon said rod and provided with aroller, the lower end of saidhandle-bar being slotted; and a clamp-levermounted in said arm and having one end adapted to engage with saidroller, said end being provided with pins said handle-bar.

2. A bench-clamp comprising the combination of a support an operatinghandle-bar mounted therein, formed with a cam-slot and provided with acam-roller and a clamplever-mounted in said support and formed with acam-surface against which rubs said cam-roller; one end of saidclamp-lever being operated by one wall of said cam-slot; one movement ofsaid handle-bar causing the wall of said cam-slot to swing saidclamplever in one direction and the reverse movement of said handle-barcausing said camroller to swing said clamp-lever in the oppositedirection.
